Shame lists will make you more enemies than kicking over a Harley at a biker bar. I've never seen one successfully put together for cannabis. As to removing the vendors, our process as of recent is just to move the threads to appropriate forums. We just about NEVER delete content; it's just moved (so it's still searchable, still index by Google, etc, we just remove the companies forum/advertising.) So the journaling/documentation is still valid, even if vendors don't stay on.If that's the case then we should have a place for the bad ones.
